PO.DAAC

The PO.DAAC is pleased to announce the public release of the (Cyclone Global Navigation Satellite System) CYGNSS Science Data Record (SDR) Version 3.2 (V3.2) Level 1 (L1) DDM calibration, Level 2 (L2) wind speed retrieval, Level 3 fully developed seas (L3 FDS) gridded wind speed, and Level 3 merged (L3 MRG) wind speed data products.

The PO.DAAC is pleased to announce the public release of Surface Water and Ocean Topography (SWOT) Ka-band Radar Interferometer (KaRIn) Science Data Products. This release includes:

• KaRIn LR oceanography products from forward processing from November 23, 2023 (Cycle 7 from science phase) onward;
• KaRIn LR oceanography and HR hydrology products from forward processing from January 25, 2024 (Cycle 10 from science phase) onward.

Reprocessing of science data products from March 30, 2023 to January 25, 2024 is ongoing. They will gradually be released as they become available over the next few weeks. 

The Surface Water and Ocean Topography (SWOT) project is pleased to announce the public release of Level 2 Geophysical Data Record products from the onboard nadir altimeter (NALT) and the advanced microwave radiometer (AMR). This release includes the Geophysical Data Record (GDR) from each of the NALT and AMR instruments. 

The NASA PO.DAAC hosted a SWOT Data Access Workshop on February 13, 2024 in Honolulu, HI in partnership with science guest speakers. 36 participants attended the half-day workshop, which included practical information on SWOT (Surface Water and Ocean Topography) hydrology data products and data access, hands-on Jupyter notebook tutorial demos in the cloud, a science workflow example, and several opportunities for participants to interact with each other, ask questions, and provide SWOT data tools and access feedback.

Please join us for the PO.DAAC town hall and presentations during the upcoming AGU Ocean Sciences Meeting, New Orleans, LA, February 18-23, 2024.

The PO.DAAC town hall scheduled for Tuesday, 20 February @ 12:45 CST features guest speaker Dr. Nadya Vinogradova-Shiffer, NASA HQ Physical Oceanography Program Scientist & Manager.

From Feb. 06, 2024, both NOAA N20-VIIRS L2P/L3U SST datasets are paused to delivery due to the L1B error. NOAA SDR team has discovered that the data quality flags at pixel level were erroneously labeled. The investigation is on-going. No new data will be released until the issue is resolved.
